The coolest item is the actor’s personal Knight Rider KITT car. This version of the iconic 1986 Pontiac Firebird wasn’t used on the the hit 1982-86 NBC show. It's a replica that was made by fans and given to Hasselhoff as a a gift. The car has the same scissor doors and W-style yoke steering wheel as the original. It also comes preprogrammed to speak over 4,000 sound bites from the show and has a "OH KITT" vanity plate. Estimate: $30,000-$50,000.

If a full-size KITT car is out of your budget, Hasselhoff is selling his replica KITT golf cart, which he used to drive his kids around on Halloween and for soccer practice. (Yes, the auction catalog really says "soccer practice.") It comes with a faux California "KNIGHT" license plate and a Panasonic sound system. Proceeds from this sale are going to be donated to the Starlight Children’s Foundation. Estimate: a modest $2,000-$4,000.

The wackiest item up for auction is an oversized (better than life-sized!) model of Hasselhoff in Baywatch swim trunks made to look like he’s gliding across the water that comes mounted on a rolling metal rack. It was used as a prop in the 2004 SpongeBob SquarePants movie. Model Hasselhoff is sporting a very weird and almost psychotic grin. Put a glass top on it and this would make the creepiest coffee table ever. Estimate: $20,000-$30,000.

Hasselhoff is also selling some of his personal clothes, including an epic full-length denim coat with fringe (est. $400-$600), a tie-dye shirt (est. $100-$200) and a denim jacket emblazoned with Disney characters, what looks like bicycle water bottle holder pockets on the back and a big “H” logo on on the front ($300-$500).
